When looking for IMO regulations on a vessel's oil water separator, the information will be found in which of the following documents?

Correct Answer: Option C — MARPOL

MARPOL Annex I, specifically Regulation 14, dictates the requirements for oil filtering equipment and oil-water separators. These international regulations govern the prevention of pollution by oil, ensuring that discharge standards are met. Compliance with these standards is mandatory for all vessels operating in international waters under IMO jurisdiction.
